Electron transport chain and DCPIP?

... reactions of photosynthesis. Anyway, I have no clue as to where in the electron transport chain DCPIP would fit in, but considering that you say cyanide increases the rate of DCPIP reduction (and since i know that cyanide blocks complex IV - cytochrome c oxidase) I would guess SCPIP sits between ...

Electron transport chain and DCPIP?

... are really confusing me; Which of the electron transport chain complexes donates electrons to DCPIP and which complex accepts electrons? Why would cyanide increase the rate of DCPIP reduction? Lastly how would i estimate the redox potential of DCPIP, what information would i need to do so? Any ...

help! my biology teacher is trying to kill me!

... final electron acceptor in the electron transport chain? a)a molecule of carbon dioxide b) a molecule of water c)an oxygen atom d) ATP e)ADP 3. Cyanide differs from dinitrophenol because cynide a) is highly toxic to human cells and dinitrophenol is nonetoxic b)is an electron transport blocker ...
